The rights to the books were originally bought by Steven Spielberg in 1991, before the founding of DreamWorks, when he thought about making a traditionally animated film based on the book. However, John H. Williams convinced him to bring the film to DreamWorks in 1994, the time the studio was founded, and the film was put quickly into active development by Jeffrey Katzenberg after the rights were bought by the studio in 1995. Shrek originally cast Chris Farley to do the voice for the title character, recording about 80%–90% of his dialog. After Farley died in 1997 before he could finish, Mike Myers was brought in to work for the character, who after his first recording decided to record his voice in a Scottish accent. The film was also originally planned to be motion-captured, but after poor results, the studio decided to get PDI to help Shrek get its final computer-animated look.
